And we are back with gerard butler. Surfing his way into theaters this friday. In a new film called "chasing maverick." It tells the true story of jay mortarty. He's a 16-year-old who takes on the most dangerous places to surf. And jerry is a man who teaching jay how to tackle the waves. Congratulations on this film. Not only are you starring in it, but you're producing. It's a passion of sorts? Yeah, it's a very inspiring, very moving, powerful story. And I thought, this is a perfect opportunity, one, for me to learn to surf. Two, tells the story for everybody. For kids, the grown-ups. The kind of movie that wants to make you eat up life. It doesn't to be surfing. Something that makes you want to tackle? I used the word "tackle" for a reason? I went to san diego with my cousin and I could barely get in the water and I thought, I'm going to make a fool of myself. Eventually, I thought it would be a sport I'd love to take up. For this film, I harnessed the idea. That explains to me how hard it is to become a surfer, how dangerous it is and how exciting it is. We actually have video in the film. You got really, really hurt. Can we roll that video that shows you -- nobody has seen that. Let's see. There you go. There we go. It was like a tsunami coming in. And then just -- look at that. That's crazy! Even though I see it now, it brings back memories. And I just didn't come back up really. I was down for that wave. And I was down for a long time, turning, turning and the next wave came over and I started to think, wow, I'm going to die making a movie. Wow, the weight of the water on you and trying to get out. Somebody described maverick's day as liquid hell. Because the water was very dark and heavy. There's just a lot of water there. It's a much deeper surf so it takes you down farther. You can go down 25, 30 feet. And it also took my board off of me. So I was just churning down there. Have you since gotten up and dusted yourself off? Yeah, yeah. I was surfing two days ago. I want to show everybody. You play a character called frosty. And you are the teacher. This is a part where jay asks you to train him to take on the maverick? One bump on the face of that wave and you're hittingater like concrete 50 miles an hour. And you have a thousand tons of water coming down on top of you. It's knocking you senseless, whipping you apart, pushing you down into a place that's so deep and so dark, you don't want to be there. So why do it? Get out of here. I got work to do. Train me then. Train me to ride it. "Chasing maverick." The flying scotsman. That's what we'll call you now on your surfboard. It's not just about surfing. You do call it a relationship film. Yeah. Tell me why. Really, this is a story, it's about following your dream. What is your dream? It's about eating up every moment. This kid came along and he just had this thing in his head, he's willing to sacrifice everything to do that. He really brought out the father figure in frosty. Frosty went through a hard time. And there was his surprising relationship that builds. And also about the people you meet in life as you're trying to achieve your dreams and your achievements. And I think that's what's really touching and surprising about the movie. Really, really a great part to the movie. We just saw images. Beautiful. We've got to go, how do we do it in surf talk, how do we go? That's it. Whenever I do it, I'll call you -- yeah, see you later. Call memaybe. Everybody check out "chasing maverick." Opens friday nationwide. And we thank you for being with us.
